Unused parameter in CXFBusImpl.shutdown(boolean wait)

[Soltysik, Seumas]

Currently CXFBusImpl.shutdown(boolean wait) takes an unused wait parameter. Is 
there any intent to make use of this parameter? If not, it should be removed.

    public void shutdown(boolean wait) {
        lifeCycleManager = this.getExtension(BusLifeCycleManager.class);
        if (null != lifeCycleManager) {
            lifeCycleManager.preShutdown();
        }
        synchronized (this) {
            state = BusState.SHUTDOWN;
            notifyAll();
        }
        if (null != lifeCycleManager) {
            lifeCycleManager.postShutdown();
        }
        if (BusFactory.getDefaultBus(false) == this) { 
            BusFactory.setDefaultBus(null);
        }
    }
